In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Notes: 1. When the P04/XT1 pins is used as an input port pin, bit 6 (FRC) of the processor clock control register (PCC) must be
set to 1. (At this time, do not use the feedback resistor of the subsystem clock oscillator circuit.)
2. When the P10/ANI0 through P17/ANI7 pins are used as the analog input lines of the A/D converter, be sure to place
the port 1 in the input mode. In this case, the pull-up resistors are automaticaly unused.
